SFDP2-050-055-42 | 5.0 GPM | 55 PSI

The SEAFLO 42 Series is a heavy-duty, 4-chamber positive displacement diaphragm pump designed specifically for high-demand water systems. Featuring Internal Bypass Technology, this pump significantly reduces rapid cycling (pulsating), providing a smoother, quieter flow even when multiple taps are in use. Engineered for the rigors of marine and RV environments, it is capable of self-priming up to 6 vertical feet and can safely run dry without damage.

RELIABILITY: Built with EPDM valves and a Santoprene diaphragm to meet or exceed OEM specifications for longevity in both fresh and salt water applications.

Key Features

✔ Internal Bypass: Reduces pump cycling for smoother flow.
✔ Self-Priming: Up to 6 feet (1.8m) vertical lift.
✔ Run Dry Capable: Safe for intermittent dry operation.
✔ Quiet Operation: Vibration-dampening rubber mounting base.
✔ On-Demand: Automatic pressure switch control.

Questions & Answers

Is this a genuine original part?

This is a genuine SEAFLO 42 Series pump, manufactured to meet highest industry standards for fitment and high-flow performance.

How do I know if it is compatible?

We recommend checking the SKU/MPN (SFDP2-050-055-42) and ensuring your system is 24V DC. If you are replacing a 3.0 GPM pump, this 5.0 GPM model serves as a high-flow performance upgrade.

What is the benefit of Internal Bypass technology?

The internal bypass allows the pump to redirect water internally when the demand is low (e.g., a tap is only slightly open). This prevents the pump from rapidly switching on and off, which reduces noise and extends the life of the pressure switch.

Note: Please verify your original part number and system voltage against the references above before purchasing. Available at 4boats.co.uk.
